C# Program to Create a Thread Pool

CsharpServer Side ProgrammingProgramming

For a thread pool, create more than two functions and queue methods for execution.

Firstly, create a method like −

public void one(object o) {
   for (int i = 0; i <= 3; i++) {
      Console.WriteLine("One executed");
   }
}

In the same way, create more methods and then use ThreadPool.QueueUserWorkItem to queue the methods for execution −

Demo d = new Demo();
for (int i = 0; i < 3; i++) {
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.one));
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.two));
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.three));
}

Example

You can try to run the following C# code to create a Thread Pool.

Live Demo

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
class Demo {
   public void one(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("One executed");
      }
   }
   public void two(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("Two executed");
      }
   }
   public void three(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("Three executed");
      }
   }
   static void Main() {
      Demo d = new Demo();
      for (int i = 0; i < 3; i++) {
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.one));
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.two));
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.three));
      }
      Console.Read();
   }
}

Output
